    NEXRAD Radar at the WSR-88D Radar Operations Center. Testbed of the WSR-88D on display at the National Severe Storms Laboratory.NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the Department of Defense. Its technical name is WSR-88D (Weather Surveillance Radar, 1988, Doppler). NEXRAD detects precipitation and atmospheric movement or wind. It returns data which when processed can be displayed in a mosaic map which shows patterns of precipitation and its movement. The radar system operates in two basic modes, selectable by the operator – a slow-scanning clear-air mode for analyzing air movements when there is little or no activity in the area, and a precipitation mode, with a faster scan for tracking active weather. NEXRAD has an increased emphasis on automation, including the use of algorithms and automated volume scans.

  • Langley Hill Doppler radar


    Langley Hill radar in August, 2011 The Langley Hill Doppler radar (KLGX) is a National Weather Service NEXRAD Doppler weather radar station on the Pacific coast of Washington State, in the United States. Prior to its construction, Washington's Olympic Peninsula coast was the only portion of the U.S. coastline without weather radar coverage, and there was "virtually no radar coverage is available over the ocean, where the majority of western Washington's weather originates" according to a Weather Service report to the United States Congress. Its location was announced in early 2011, construction started in March, and the unit was commissioned in September, 2011. A major motivation for the station was early detection of Pacific Northwest windstorms; a proponent, Professor Cliff Mass of the University of Washington, said it would provide an additional 6 to 12 hour storm warning to residents of the Pacific Northwest.
